Ladies & Gents,
The above has a very thorough 8 page build article on HMLS Kia-Ora by Pete Heath, based on the Takom Mk.I Female.
It is a nice build, with pitfalls of the kit overcome and Mk.I / Gaza features comprehensively tackled.
There are some minor misunderstandings or poorly observed details, but still about the best WWI tank article I've seen in a modelling magazine.
Certainly it is VERY rare that I part with £5 unless a magazine bears repeated reference / scrutiny, so let that be recommendation enough for you.
